Q.
How the heck did you figure out where it was?

A.
This scene is so brief and so dark, that I didn't spend much time
looking for it back when I was first finding the locations from the
first season. I actually thought it might be in Miami, since they
had filmed there for the first few episodes.

All I knew is that a number on the front porch (seen as Matt pulls up in his car) seemed to read 1336.

But
they have filmed on that street so often in the past, that I've become
acquainted with its "look" in the years since, and when I rewatched the
second episode in 2011, I immediately knew it was probably Gordon Street.

I checked Google StreetView,
but that didn't help much, because the trees & bushes in front of
the house had grown so much since then that you can't really see the
house in the StreetView. You can only see driveway where Matt parked, and (if you pan to the left) the same large palm tree (just north of the home) where Dexter parked.

Fortunately,
though, I was able to find the photo above, from a real estate listing,
and sure enough, it showed the same black numbers right below a narrow
opening on the porch, next to the door.
